One-Note Wonder

It was the manakin’s simple song that gave it away. Rather than the two-note chirp of its close relatives, the striped manakins from other areas of South America, the tiny bird with the red cap trilled out only single syllables.

The new species song could only be compared to other species once vocalization samples from other manakin groups had been recorded. It was only then that researchers were able to hear that M. eckelberryi song was so different from other manakin species. When they dug deeper, they found other defining characteristics as well.

Attention to detail, patience, and research funding led to this new identification.

But more than that, even before the manakin was revealed to be a new species, the researchers’ revelation of the spectacular biodiversity of this habitat led to the creation of one of Peru’s largest national parks. The Cordillera Azul National Park covers 13531 km² (522 m²) and is home to a remarkably untouched variety of flora and fauna.

What other discoveries, what unique songs, lay in wait in collections around the world?
